Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the insulation is not considered an enamel but a different type of varnish
The distinction between enamel and other insulation types can be technical; if Formvar is not accepted as enamel, it would fall under other insulated wire.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right tariff item — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Provide a detailed technical datasheet to the CBSA officer demonstrating the Formvar insulation and copper conductor
• Since Formvar is a specific type of enamel, ensure the documentation clearly states this to avoid misclassification
